Abstract
The utility model discloses a kind of water pump bearing body gland sealing devices, are made of retaining ring, bearing body gland and reinforced seal；The retaining ring, bearing body gland and reinforced seal are concentric, and before retaining ring is mounted on bearing body gland, the outer diameter of reinforced seal is mounted in bearing body gland by interference fit, and reinforced seal and bearing body gland binding face have sealant.Using reinforced seal, can be effectively prevented external water, dust and the intrusion of other harmful substances matter, and caused by the appearance of bearing failure situation more securely and reliably guarantee the sealing effect of water pump bearing body, reduce overhaul of the equipments rate, improve the service life of equipment.
Description
Technical field
The utility model relates to a kind of sealing devices, and in particular to a kind of water pump bearing body gland sealing device.
Background technique
Water pump is the equipment for being promoted and conveying liquid, and bearing body is the component for supporting pump shaft, and bearing is installed on axis
It holds in seat, as rotatable parts, bearing body is the important support of water pump and positioning element.
The water pump is that turbid loopback water promotes pump group, which is promoted to turbid loopback water at secondary iron sheet sedimentation basin
Reason.Since, containing impurity such as iron filings, the grains of sand, after water pump packing abrasion, water, which largely flows into, to catchment in the turbid circulating water of pump group conveying
Slot, sewage pipe row do not come, and water can enter bearing body, cause emulsification of lubricating oils, go bad, and do not have lubricant effect, the later period is also
The failure of bearing will be caused, water pump is caused to be unable to operate normally.If replacing the packing on the inside of water pump gland ring, need to open pump
Shell just can be with, larger workload, and difficulty of cutting off the water is big.
In addition, since equipment is old, the valve that absorbs water out can not be closed tight when overhaul of the equipments, causes a large amount of water to enter and catchment
In slot, drainpipe row does not come, and catch basin internal water accumulation enters in bearing body, and (ponding is high when the water at water pump catch basin is more
Degree is more than the position of axis), retaining ring does not just have the effect of water blocking, and water will flow in water pump bearing body along the position of axis,
The water pump bearing service life is impacted.
Summary of the invention
The purpose of this utility model is to provide a kind of water pump bearing body gland sealing devices, to solve existing pump shaft
Hold the problem of body gland leakproofness difference.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of water pump bearing body gland sealing device is made of retaining ring, bearing body gland and reinforced seal；The water blocking
Circle, bearing body gland and reinforced seal are concentric, and before retaining ring is mounted on bearing body gland, the outer diameter of reinforced seal passes through interference
It is fitted in bearing body gland, reinforced seal and bearing body gland binding face have sealant.
Rotational symmetry component, internal diameter are matched with pump shaft centered on above-mentioned retaining ring.
Above-mentioned bearing body support frame is center symmetrical parts, and internal diameter is matched with pump shaft.
Above-mentioned reinforced seal is center symmetrical parts, and internal diameter is matched with pump shaft, using self-tightening type lip seal.
Above-mentioned retaining ring, bearing body gland and reinforced seal concentricity are between 0.24-0.28mm.
The surface roughness of above-mentioned pump shaft and reinforced seal contact position is between 0.4-0.8.
Above-mentioned pump shaft and reinforced seal contact position have lubricating grease.
The utility model has the advantages that
External water, dust can be effectively prevented using reinforced seal in the utility model water pump bearing body gland sealing device
With the intrusion of other harmful substances matter and caused by the appearance of bearing failure situation more securely and reliably guarantee the close of water pump bearing body
Effect is sealed, overhaul of the equipments rate is reduced, improves the service life of equipment.
Detailed description of the invention
Fig. 1 is a kind of installation diagram of water pump bearing body gland sealing device of the utility model.
In figure: 1, pump shaft；2, reinforced seal；3, bearing body gland；4, retaining ring.
